Performance comparison between IPv4 and IPv6 on the Internet.

We asked ourselves: What is the difference between IPv6 and IPv4 performances in today's Internet?
IPv4 $ ping -n -c3 ietf.org PING ietf.org 64 bytes from 64 bytes from 64 bytes from

It seems that there is a problem... Would it be a routing problem? A configuration problem? First things first... We are not even testing it the right way... How can we measure it in a more significative way?
RIPE TTM Data! (http://ttm.ripe.net) They have a lot of dual stack measurement boxes over the world, and a cool IPv6 tunnel discovery tool...

OK It seems a lot better than the pings... Why? Do we have a problem within the Brazilian networks? Would this data be distorted because TTM boxes are generally in the core of the networks?

Good news: in the general picture, IPv6 is production quality! Not so good news: “production quality” for IPv6 and IPv4 could be a bit alike and better... Yes, it seems we do have a problem with Brazilian upstreams and specific destinations, for example US. Why? We do no know yet. Why IPv4 is worst sometimes? Why so many differences in the hop number (routes) comparing v4 and v6?
Next steps... You can access the data: http://labs.ceptro.br/ccl-ipv6 http://labs.ceptro.br/simonv6 We can discuss it:
